DISASTER!

I’m starting to, as well…

 

Get your proper measuring head on, mate Nip down to Screwfix in the morning and get a pair of less jittery calipers...

 

I don’t know.

 

Don't give up yet. Just need some accurate measurement.

 

You know, I only did the latter measurement just now.Running outside in the rain and unlocking everything.
My minds not really on it,tbh. Been up since 5.30 and worked all morning. Shagged out now.

 

And my middle son is getting picked up at 2.00am, so I doubt if I will sleep much from now until after he has gone. I’ll try all this again tommorow.

 

Time for bed said zebedee.

 

Is it worth going up Tool and Gauge and see if they would measure it for you.

If not I could come and have a look I’m no expert though.
I’m busy this week and camping the weekend but could next week or drop it around sometime and I will look when I can.

 

Morning.
So to me, or wha I can read of it a STD marked bearing, refers to the cranksize being standard, ie no regrind, but with a none standard outer diameter to accommodate a align bore View attachment 134298

 

You been up to Tool and Guage recently?

 

OK, I'll humour you. Where on your bearing that you pictured that is just marked STD does it show the non-standard outer dia?

And it's "line" bore, not "align" bore.

 

Ok. Measuring head on, this is as good as it’s gonna get.

 

So, according to my Lidls calipers, it has had a 0.5 align a line alight a long bore…
Even the ruler shows 0.5 after the 65mm if you look closely.

 

I’ll look later. Have to go to work now and clear a third of an Acres worth of bramble. Might rip myself to shreds, but hey.

 

This is one half of the shell, which when put together with the other half, measures at 65.50 or thereabouts. Standard crank size, 0.5 oversize outer. Humoured now?

 

Confused

 

A lot has happened while I've been in bed. Calipers are not the correct tool or accurate enough to measure what you are trying to measure but FWIW the witness marks on the back of that bearing and the crankcase suggest it is correct size. If the bearing was 0.5 over and the case standard you wouldn't get the two halves together. If the case was 0.5 over and the bearing standard it would rattle about.

 

Tell me about it!

 

Thank you. Yes, I know this, but it’s all I have, and get, it’s obvious it wouldn’t fit, like a size 9 1/2 foot, in a size 9 shoe, so to speak… sort of…
